I have been running 93 octane fuel since the vehicle was new (about 1 year). In my head, turbo vehicles always use premium fuel, and that is what we always put in since new. I happened to be looking for something unrelated in the owners manual, and saw that 87 fuel is fine. Since it is nearly $1 a gallon cheaper currently where I live, I figured why not use it instead if all I am getting is a little loss of power. That evening, check engine light came on. Unfortunately I cannot find my scan tool at the moment, but in the Ford App, it says that I have an issue with my catalytic converter.
Two questions for the forum. 1) Does it seem logical that using 87 suddenly instead of 93 has caused a check engine light? 2) Are the messages in the Ford App actually accurate to a specific cause, or is that a generic message? For instance, if it was actually a misfire, would it indicate a misfire.
I already have an appointment with the dealer next week for many other issues I am having with the vehicle, so I am definitely taking it in, but I was just curious if anyone had any thoughts in the meantime.
